CYPROHEPTADINE HYDROCHLORIDE vs DISOMER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cyproheptadine is a potent antihistamine (H1 receptor antagonist) and antiserotonergic agent (5-HT2 receptor antagonist). It also exhibits weak anticholinergic and sedative properties. It blocks histamine-mediated vasodilation, increased capillary permeability, and pruritus, as well as serotonin-mediated effects on appetite and mood.
Selective dopamine D2 receptor antagonist; also blocks alpha-1 adrenergic, histamine H1, and muscarinic M1 receptors.
4 mg orally three times daily; range 4-20 mg/day, not to exceed 0.5 mg/kg/day
Adults: 1 mg orally once daily.

Terminal half-life approximately 8–16 hours in adults; may be prolonged in elderly or hepatic impairment.
12–15 hours in adults with normal renal function; prolonged to 30–40 hours in severe renal impairment (CrCl <30 mL/min).
Primarily renal (appreciable unchanged drug and metabolites); biliary/fecal elimination minor (<5%).
Renal: 80% as unchanged drug; biliary/fecal: 15% as metabolites; <5% unchanged in feces.
